Because they have different dose-limiting adverse effects, they can be given together at full doses in chemotherapy regimens. [1] The first successful combination chemotherapy was MOPP, introduced in 1963 for lymphomas. The term "induction regimen" refers to a chemotherapy regimen used for the initial treatment of a disease.
The diminished reactivity limits protein-carboplatin complexes, which are excreted. The lower excretion rate of carboplatin means that more is retained in the body, and hence its effects are longer lasting (a retention half-life of 30 hours for carboplatin, compared to 1.5-3.6 hours in the case of cisplatin).
A dose–response curve is a coordinate graph relating the magnitude of a dose (stimulus) to the response of a biological system. A number of effects (or endpoints) can be studied. The applied dose is generally plotted on the X axis and the response is plotted on the Y axis. In some cases, it is the logarithm of the dose that is plotted on the ...
Second, the drug dose the patient received, and if its amount is commensurate with developing CIPN, must be considered. [1] The immunomodulatory drug bortezomib, for example, is more likely to cause neurotoxicity in a cumulative dose of 20 grams. Finally, the characteristics and the duration of a patient's symptoms should be analyzed.
A dose-volume histogram (DVH) is a histogram relating radiation dose to tissue volume in radiation therapy planning. [1] DVHs are most commonly used as a plan evaluation tool and to compare doses from different plans or to structures. [ 2 ]
In the clinic, a maximum recommended cumulative dose is set for anthracyclines to prevent the development of congestive heart failure. [35] As an example, the incidence of congestive heart failure is 4.7%, 26% and 48% respectively when patients received doxorubicin at 400 mg/m 2 , 550 mg/m 2 and 700 mg/m 2 . [ 4 ]
The drug methotrexate (bottom) is an antimetabolite that interferes with the metabolism of folic acid (top). An antimetabolite is a chemical that inhibits the use of a metabolite, which is another chemical that is part of normal metabolism. [1]
Diagram of a catalytic reaction, showing the energy level as a function of the reaction coordinate. For a catalyzed reaction, the activation energy is lower.. In chemistry, a reaction coordinate [1] is an abstract one-dimensional coordinate chosen to represent progress along a reaction pathway.
